ROYAL evo 7
8.5.2.
This is NEW
The ROYALevo7's battery management feature con-
stantly monitors the state of charge of the transmitter
battery - even when the unit is switched off.
In detail the system works as follows:
a.
when charging
If the transmitter battery is charged via the charge
socket at more than about 50 mA, the transmitter
electronics constantly measure the charge current
and calculate the charge quantity fed into the bat-
tery. This value is stored in the transmitter.
b.
in use
The current is also constantly measured in use; the
transmitter calculates the consumed charge and
deducts it from the available charge. The status
display 3 (
10.7.) then shows the available bat-
tery charge.
The transmitter also calculates and displays the re-
sidual operating time (but only when an RF sig-
nal is transmitted, otherwise the screen displays
"---" for residual time). This value indicates how
long the transmitter can work at the present cur-
rent drain.
c.
when the transmitter is switched off
The transmitter battery loses about 1.5% of its
charge every day through self-discharge, even
when stored unused in your workshop. The battery
management system takes self-discharge into ac-
count and corrects the displayed battery charge.
!
The battery charge and residual operating time are
only displayed for your information. Manufactur-
ing tolerances and variations in battery mainte-
nance can cause wide variations to occur.

You must take this into account
To ensure that the battery management displays values
which come as close as possible to "the true situation",
you must observe the following points:
a.
Correct the battery charge
The battery management circuit assumes that a
1500 mAh battery is installed in the transmitter. If
you fit a battery of larger capacity (for example),
you will need to enter the new capacity in the ap-
propriate menu
Menu: L , Transmitter Parameter: Battery
charge
Here you can enter the capacity value found by
your charger (in increments of 50 mAh).
!
If battery voltage falls below 6.5 V, the avail-
able charge is set to 0 mAh.
b.
Charging the battery via the charge socket
The transmitter electronics can only monitor the
state of charge if charging takes place via the
charge socket. Read the charging notes (
c.
Normal charging at constant current (1/10 C)
If the battery is left connected to the charger longer
than the time calculated with the formula in Sec-
tion 8.2, the battery manager still only shows a bat-
tery charge of 1500 mAh.
d. If you always charge up the battery in the transmit-
ter, and always to 100%, the displayed capacity will
remain accurate over many charge cycles. Even so,
you should check the display from time to time af-
ter charging, as inevitable tolerances may cause
deviations in the course of time.
e.
If the screen shows less than 90% of the nominal
battery capacity immediately after charging, the
battery is exhausted, and should be replaced by a
new, genuine MULTIPLEX transmitter battery.

Recycling
NiMH cells do not contain environmentally harmful
cadmium, but they should still not be disposed of as or-
dinary household waste. Take the cells to your local re-
cycling centre. Be sure to discharge the cells before-
hand, and protect them from short-circuit (e.g. wrap
them in plastic film).
